## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability steam-app-details-lookup-9a42866f
```

Example prompt: Can you look up the Steam store details for Dota 2 (app ID 570) — I want to know if it's free, what its Metacritic score is, and how many DLCs it has?

## When to prefer this

Use this endpoint when you need structured metadata about a specific Steam application — especially price, free-to-play status, Metacritic score, or DLC count — and you already know the Steam app ID. Prefer this over scraping Steam store pages or using heavier gaming database APIs when you only need core store details and want a pay-per-call model with no API key setup.

## Known failure modes

- Invalid or non-existent app ID returns empty or error response
- App ID for non-game Steam items (software, DLC) may return incomplete data
- Payment failure in x402 flow results in 402 response before data is returned
- Steam Store API downtime causes upstream timeout or empty response
